Found in New Guinea in montane forests at elevations of 1000 meters as a medium sized, warm to cool growing epiphyte with a short rhizome giving rise to somewhat compressed, densely leafy stems carrying erect-patent, oblong-ligulate, obtuse and shortly bilobulate apically, rounded basally leaves that blooms in the late summer and early fall on an erect, capitate, .8 " [2 cm] wide, few flowered inflorescence.

Schlechter states that this species is closely related to A fragrans but differs in the anther that is thickly covered with large warts, broader leaves, broader sepals and petals, a shorter and narrower lip claw with a larger lamina and a broader shorter column
